Engineering Internship & Environmental Health & Safety Leadership — Proterra; Greer, Sc

Embedded Systems Validation Engineering Intern

The Embedded Systems Validation Engineering Intern will create automated tests and processes for Proterra’s Battery Management Software (BMS). This internship provides hands‑on experience in testing battery management software and battery electronics while building out an automated test suite and related processes to be used in current and future products.

The intern will validate BMS embedded software behavior, fault handling, and communication protocols across a range of test environments, including simulated hardware‑in‑the‑loop (HIL), various bench test setups, and full battery‑pack configurations as active elements in the test loop. The intern will also participate in Energy Storage Systems (ESS)‑level validation reviews and test coverage audits.

The Environmental, Health & Safety (EHS) Engineer will lead critical initiatives that protect our people, our facilities, and our environment at Proterra’s Greer manufacturing site. This role drives EHS program development, regulatory compliance, ISO 14001 management, incident prevention, and continuous improvement across operations. The EHS Engineer partners closely with Production, Maintenance, Engineering, and Leadership to strengthen our safety culture, reduce risk, and support sustainable, high‑quality manufacturing.
